Proteus Cable, fake warning - Page 5

Why do you keep making reference to "shield"? The term is irrelevant to this particular discussion.

 

Again, both RCA and XLR interfaces require a minimum of two traditional conductors. Shielding is optional in both cases.

 

And just to remind you what this particular discussion is, it has to do with your following claim:

 

The minimum amount of conductors for an RCA cable is 1 (signal). The minimum amount for an XLR cable is 2 (hot, neutral).

He was rather upset when he received his order.

 

Apparently this is their idea of a "spool."

A 10 inch diameter "cotton ball."

LOL, that is one of the funniest things I've seen in some time.  Thanks.  At least your friend shouldn't have too much trouble pulling off the end and cut for use; he'll just need to devise a holder/dispenser of some type for that ball :)

Wow !?! So that's it, it's fake, end of story ?

 

Nevermind the fact that the original article doesn't mention anything about a fake cable, nor the fact that the owner actually bought another PAD cable one year later ?

 

Now if that was me, and I was thinking something was wrong with my 4000$ cable, I wouldn't go back to the same manufacturer for anything.

I can't believe they had the balls to send you that.

 

RCAs by design don't need to have an external shield.  Some that are based off coax cable use a shield as the return.  XLR is supposed to have a shield that is tubular and goes around the twisted pair of conductors inside; the shield probably should not be a traditional conductor since the point of it is to pick up interference and drain it off.  You can put a shield on an RCA cable all the same, but you only connect it at one end to drain it, as you don't want the shield to be the return conductor as well for the RCA, and there isn't a dedicated pin just for the shield like on the XLR.

I think we're just arguing semantics here. I know that shielding is optional on an RCA cable. Shielding is not optional on a coaxial cable though, and when you reduce a single-ended interconnect to its most minimal form, you're left with coax. What I should've said is that the minimum amount of conductors required for an RCA cable is a center conductor and a shield. You cannot make a cable with just a center conductor.

Or a simple pair of wires.

 

Just as shielding isn't a requirement, neither is a coaxial geometry.

No, what you should have said was that the minimum number of conductors required for an RCA cable is two. Same as for an XLR cable. There's no difference between the two other than the connectors used.

"Center conductor" has absolutely nothing inherently to do with the issue of an RCA cable versus an XLR cable.
